Atomic Heavy Duty Timing Chain – Ford Barra DOHC | Double Row | High Tensile | Suits OEM & Vernier Gears
Description:
The factory single-row 8mm pitch Simplex timing chain in Ford Barra DOHC 6-cylinder engines is adequate for stock setups — but in high-performance builds, it quickly becomes a known weak point.
The Atomic Heavy Duty Timing Chain solves that with a double-row true roller design offering nearly twice the tensile strength of the OEM chain. Constructed with 50–60% thicker locking plates, it resists stretch and chain whip even in engines with heavier valve springs, higher RPM, and big boost.
Each chain includes timing marks for easy alignment, fits directly onto OEM or Atomic Vernier sprockets, and is stamped with the Atomic "A" so you know you're running the real thing. Installation instructions are included to ensure a precise, drama-free upgrade.
